Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

Abstract: In some examples, an optically active article includes a retroreflective substrate; and at least one security element disposed at the retroreflective substrate; an article message disposed at the retroreflective substrate, and wherein the at least one security element comprises validation information that is detectable outside a visible light spectrum, and wherein a combination of the article message and the validation information of the at least one security element indicates whether the optically active article is counterfeit.

Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

Abstract: The disclosure describes an example vehicle assistance system including a light sensor, a pixelated filter array adjacent the light sensor, and a full-field optically-selective element adjacent the pixelated filter array. The optically-selective element is configured to selectively direct an optical component of light incident on the optically-selective element across the pixelated filter array to the light sensor.

Abstract: Optical constructions are disclosed. A disclosed optical construction includes a reflective polarizer layer, and an optical film that is disposed on the reflective polarizer layer. The optical film has an optical haze that is not less than about 50%. Substantial portions of each two neighboring major surfaces in the optical construction are in physical contact with each other. The optical construction has an axial luminance gain that is not less than about 1.2.

Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses selectively located barriers to the adhesive regions. A structurally weak wavelength-selective material includes portions that contact the adhesive regions and break to remain in contact with the adhesive. The wavelength-selective material does not contact the adhesive regions covered by the barrier and is removed leaving a wavelength-selective film in a pattern at the adhesive regions.

Abstract: The disclosed structured retroreflective article includes a symbol aligned with raised regions of the structured retroreflective article through an orientation mark which aligns the symbol to the raised region. In one embodiment, the retroreflective article comprises a substrate comprising a background surface and a raised region, a retroreflective film comprising a first symbol and an orientation mark, wherein the retroreflective film is applied to the substrate and the orientation mark aligns the first symbol to the raised region.
